Title: Continuous production of neutralized olefinsulfonic acid having high concentration
Inventor: ANDO HIDEO
IPC: C07C67/00
Filed: 1984-08-30
Abstract: PURPOSE:To obtain the titled compound in high purity at a low cost, by carrying out the neutralization while supplying an olefin sulfonation reaction product in a manner to keep the surfactant concentration in the reaction product, the residual unreacted base content, and the surfactant concentration in the recycled neutralization product within respective specific ranges. CONSTITUTION:The sulfonation reaction product of a 10-20C olefin and a basic substance (e.g. aqueous solution of sodium hydroxide) are supplied continu ously by te feed pumps 1 and 2 to a mixing apparatus 3 in a manner to keep the surfactant (AI) concentration in the neutralization product to 40-60wt%, and keep the amount of the residual unreacted basic substance to 2-10wt% based on AI. The neutralization mixture is transferred to the recycling system 7 and neutralized under the condition to keep the AI concentration to >=65wt% after recycling to the mixing zone 3. A neutralized olefinsulfonic acid having high concentration can be produced by this process. There is no remarkable gelation or thickening of the product, and since the neutralized product is always kept from acidic state, the corrosion of the apparatus can be prevented.

Filed: 1989-07-13
Abstract: PURPOSE:To obtain the color sepn. filter which is free from unequal film thicknesses and unevenness colors by forming resin patterns on such a manner that a resin remains uniformly in the parts bordering colored regions. CONSTITUTION:A coating film 6 is formed on a glass substrate by spin coating and drying of an aq. soln. consisting of gelatin-ammonium dichromate. Photoli thography is executed by using a photomask having light shielding parts to form the patterns 7; thereafter, a coating film 8 is formed again by the spin coating and drying of the aq. soln. The photolithography is executed by using the photomask having the light shielding parts to form the patterns 9. The patterns are then colored by a red dye to form patterns 10 and thereafter, the positions of the patterns are shifted and the formation is repeated twice by changing the coloring agents to green and blue, by which the color sepn. filters added with the green colored patterns 11 and the blue colored patterns 12 are produced.

Title: Production of artificial rock crystal
Inventor: TAKASHIMA HEIJI
IPC: C30B29/18
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent artificial rock crystal from being intervened by foreign matter particles originated from a metal component by charging raw material rock crystal into an aqueous solution of alkali to keep hydrothermal environment and recrystallizing rock crystal on a seed rock crystal covered with a polymer raw material formed in mesh-like state through which rock crystal component can pass. SOLUTION: Waste rock crystal as a raw material rock crystal and a seed rock crystal are charged into a dilute aqueous solution of alkali in an autoclave and these crystals are heated to a prescribed temperature to retain hydrothermal environment having high pressure and high temperature. Thereby, rock crystals are recrystallized on the seed rock crystal to provide the objective artificial rock crystal. At this time, the seed rock crystal 12 immersed in an aqueous solution of alkali is housed in a mesh package 10 composed of a body 10a and a lid 10b and fixed to an outside growing frame 16 made of metal through wires 13 and 14 inserted into holes 11 and 15. The mesh package 10 is composed of a heat-resistant and corrosion resistant polymer raw material such as fluororesin and the sieve opening of mesh is formed so as to have about 10 μm size. Thereby, molecular rock crystal can be passed through the opening, but penetration of large-size foreign matter particles of by- product mineral produced from the metal component is prevented and foreign matter density of the artificial rock crystal is reduced.
